Q & A

What is the function of an Erlenmeyer flask in a laboratory?

An Erlenmeyer flask is used as a container for preparing and mixing specific solutions, and it can also serve as a container for titration.

What is the primary use of a beaker in a chemical laboratory?

A beaker is primarily used as a container for stirring, mixing, and heating liquids.

How does a dropper (pipet tetes) differ from other liquid transfer tools in the laboratory?

A dropper is used to transfer liquids in small, precise drops, making it suitable for handling tiny volumes of liquid.

Why is a graduated cylinder (gelas ukur) important in laboratory work?

A graduated cylinder is crucial for accurately measuring the volume of liquids in precise amounts, usually in conjunction with a dropper.

What is the purpose of a test tube in chemical reactions?

A test tube is used to hold and heat substances during chemical reactions, typically in small quantities.

What role does a volumetric pipet play in the laboratory?

A volumetric pipet is used to transfer specific volumes of liquid accurately, according to the labeled volume on the pipet.

What is the function of a porcelain evaporating dish?

A porcelain evaporating dish is used to evaporate liquids or dry wet solid substances.

What is the safety significance of wearing protective equipment in a laboratory?

Wearing protective equipment such as a lab coat, goggles, gloves, and closed-toe shoes is essential for safeguarding oneself from chemical spills, splashes, and exposure to hazardous materials.

Why should chemicals not be smelled directly in the laboratory?

Chemicals should not be smelled directly because harmful fumes or toxic gases may be inhaled. Instead, wafting the air with a hand helps to detect odors safely.

What safety precautions should be taken when handling strong acids or bases in a laboratory?

When handling strong acids or bases, they should be added to water, not the other way around, to prevent violent reactions. Additionally, gloves and goggles should be worn, and the work should be performed in a fume hood if necessary.
